FIG. 1 illustrates an example in which a device 100 according to some embodiments receives a user input and generates printing information.

As shown in FIG. 1, a printing information providing system according to an embodiment of the present invention may include the device 100, a server 110, and a printer 120.

The device 100 may receive a user input. A user input according to an embodiment may be used to generate printing information. For example, the device 100 may acquire a basic image by using the user input and generate printing information by using the acquired basic image.

A basic image according to an embodiment is basically used to determine a target article. The basic image may be acquired according to a user input for acquiring an image.

For example, the basic image may include an image that is acquired via a sketch input. A sketch input according to an embodiment may denote an input obtained by a user performing a sketch via a touch on a screen where a touch input is possible. A sketch input according to another embodiment may denote an input obtained by the device 100 recognizing a sketching operation of a user.

As another example, the basic image may include an image acquired via photography according to a user input. For example, a desk image captured according to a user input of performing photography may be a basic image.

As another example, the basic image may include an image downloaded from a server according to a user input. For example, a chair image downloaded from a server according to a user input may be a basic image.

The device 100 may acquire a 3D article list from the server 110. The 3D article list may include information about a plurality of 3D articles. The device 100 may determine a target article corresponding to the basic image the 3D article list acquired from the server 110.

A target article according to an embodiment is an article that is to be edited. The target article may denote an article that is determined from the basic image based on similarity with the basic image from among the 3D articles included in the 3D article list. For example, the target article may denote an article corresponding to the basic image from among the 3D articles included in the 3D article list. As another example, the device 100 may select a 3D article having a most similar shape to the basic image from among the 3D articles included in the 3D article list, and may determine the selected 3D article as the target article. Whether the shape of the 3D article is similar to the basic image may be determined according to a predetermined criterion. As another example, the device 100 may select, as the target article, a 3D article that is included in the 3D article list and is most frequently used from among 3D articles having similar shapes to the basic image. A frequency of usage according to an embodiment may denote a frequency of exposure to the Internet. Being similar in shape according to an embodiment may denote a case where a shape similarity is equal to or greater than a predetermined reference when being determined according to a predetermined manner. For example, the device 100 may express a similarity between the shape of the basic image and that of a 3D article included in the 3D article list as a numeral between 0 and 100.

A target article according to another embodiment may denote an article that is selected based on a user input from among the 3D articles included in the 3D article list.

The device 100 may provide a graphical user interface (GUI) capable of editing the shape of the target article. The device 100 may edit the shape of the target article, based on an edition input which is a user input via the provided GUI. The device 100 may generate printing information used to 3D print the edited target article. The printing information is used to perform printing. The printing information may be generated by the device 100 and transmitted to the printer 120. According to an embodiment, the printer 120 may include a 3D printer.

According to an embodiment, the printer 120 may generate an edited target article 130 by using the printing information received from the device 100.

According to another embodiment, the printer 120 may generate the edited target article 130 by receiving printing information transmitted by the device 100 to the server 110 from the server 110.

According to an embodiment, the device 100 may store the 3D article list. For example, the device 100 may acquire information about 3D articles from the server 110 and store the acquired information. The information about the 3D articles may include information related with the 3D articles, such as images of the 3D articles and names of the 3D articles.

According to another embodiment, the device 100 may store information about the target article and information about connection relationships between the constituent articles included in the target article. The constituent articles may denote articles that constitute the target article. For example, since a chair may be formed of a chair back, a seat, and legs, the chair, which is a target article, may be formed of constituent articles which are the chair back, the seat, and the legs. In this case, the device 100 may store information about a relationship between the chair back and the seat and a relationship between the seat and the legs.

According to another embodiment, the device 100 may store weight information of the constituent articles included in the target article. For example, the device 100 may store respective weights of the constituent articles of the target article with preset accuracy. The preset accuracy may vary according to settings.

According to another embodiment, the device 100 may store information about at least one of directions and ranges in which the constituent articles included in the target article respectively move according to the function of the target article. For example, the device 100 may store information about a direction in which and an angle at which the back of the chair is tilt.

According to another embodiment, the device 100 may store information about the constituent articles included in each of the 3D articles stored in the device 100.

For example, the device 100 may index each of the constituent articles. In this case, the device 100 may store a result of the indexing.

As another example, the device 100 may store information about joins between the constituent articles. According to an embodiment, when the target article is a chair, the device 100 may store information about a join between a chair back and a seat of the chair. The device 100 may display the information about the joins. A method of displaying the information about the joins will be described later with reference to FIG. 12.

As another example, the device 100 may store information about operations of the constituent articles included in the target article. The meaning of the information about the operations of the constituent articles will be described later with reference to FIG. 22.

As another example, the device 100 may store information related with a method of assembling the target article by using the constituent articles. The information related with the assembling method will be described later with reference to FIGS. 15 and 16.

FIG. 2 is a flowchart of a method in which the device 100 according to some embodiments generates 3D printing information.

In operation S210, the device 100 may acquire a basic image. According to an embodiment, the device 100 may acquire the basic image, based on a user input for acquiring an image.

For example, the device 100 may acquire the basic image via a user input acquired by performing a sketch via a touch on a screen where a touch input is possible. As another example, the device 100 may acquire the basic image by recognizing a sketching operation of a user. As another example, a desk image captured according to a user input of performing photography may be a basic image. As another example, a chair image downloaded from a server according to a user input may be a basic image. In operation S220, the device 100 may determine a target article. For example, the device 100 may determine a target article corresponding to the basic image acquired in operation S210 from the 3D article list stored in the device 100. The meaning of the target article corresponding to the basic image has already been described above with reference to FIG. 1.

The device 100 may use image parts when determining the target article. The image parts may mean a plurality of image parts into which an image is split. For example, when the basic image is a chair image, a chair back image, a seat image, and a chair leg image into which a chair image is split may be image parts for the basic image.

According to an embodiment, the device 100 may use the image parts of the basic image when determining the target article corresponding to the basic image from the 3D article list. For example, the device 100 may split the basic image into a plurality of image parts and an image of each of the 3D articles included in the 3D article list into a plurality of image parts according to a predetermined criterion and compare the image parts of the basic image with the image parts of each of the 3D articles, thereby determining the target article corresponding to the basic image. For example, when the device 100 acquires a first image and a second image by splitting the basic image, acquires a (1-1)th image and a (1-2)th image by splitting a first 3D article, and acquires a (2-1)th image and a (2-2)th image by splitting a second 3D article, the device 100 may compare the first image with the (1-1)th image, the second image with the (1-2)th image, the first image with the (2-1)th image, and the second image with the (2-2)th image and thus may determine the target article corresponding to the basic image from among the first 3D article and the second 3D article.

According to another embodiment, the device 100 may provide a selection menu for selecting an image corresponding to the basic image from the images of the 3D articles included in the 3D article list. For example, the device 100 may display a predetermined number of images that are similar to the basic image from among the images of the 3D articles included in the 3D article list. Similarities between the images of the 3D articles and the basic image may be determined according to a predetermined manner. For example, the device 100 may determine similarities between the images of the 3D articles and the basic image, by using the above-described image parts.

According to an embodiment, the device 100 may receive a selection input with respect to one of the displayed images of the 3D articles and determine the selected 3D article image as an image of the target article.

The basic image and the image of the target article may share similar features.

In operation S230, the device 100 may provide a GUI capable of editing the shape of the target article. According to an embodiment, the device 100 may provide a GUI capable of editing the shape of the target article according to a user input.

According to another embodiment, the GUI of the device 100 may provide an edition menu for editing a specific part of the basic image. The shape of the target article may be edited based on a user input via the GUI.

According to another embodiment, the device 100 may provide a recommendation list of constituent articles that are compatible with the constituent articles included in the target article. For example, when the target article is a chair, the device 100 may provide a recommendation list of a chair back which is a constituent article included in the chair. In this case, a chair back from among a plurality of displayed back chairs may be determined based on a user input. For example, a chair back image from among a plurality of displayed chair back images may be selected according to a selection input of a user.

The device 100 may provide the recommendation list according to a predetermined criterion. For example, the device 100 may provide the recommendation list of compatible constituent articles, based on stability of the target article edited by the constituent articles included in the recommendation list. The target article edited by the constituent articles included in the recommendation list may mean a target article that has been edited to include one of the constituent articles included in the recommendation list as a component of the target article. For example, when the target article is a chair, the edited target article may mean a chair of which legs are replaced with legs included in the recommendation list.

Stability of an article according to an embodiment may mean a value representing a degree to which the shape or location of the article is maintained without being deformed when an external force is applied to the article.

When a constituent article included in the recommendation list is used as a constituent article of the target article, stability of the target article may be maintained to a predetermined reference or greater. For example when the device 100 provides a recommendation list for wooden legs which are a constituent article of an office chair, which is a target article, the device 100 may include only wooden legs of which stability is equal to or greater than a predetermined reference when being used in the office chair, which is the target article, in the recommendation list. Stability of the office chair edited by wooden legs included in the recommendation list may be maintained to a predetermined reference or greater. The office chair edited by the wooden legs included in the recommendation list may mean an office chair including, as a constituent article, wooden legs included in the recommendation list. Stability of an edited target article according to an embodiment may be determined based on at least one of a location of the center of gravity of the target article edited by a constituent article included in a recommendation list and an internal structure of the target article. For example, a height of the center of gravity of a desk edited by a chair back included in a recommendation list may serve as a criterion for determining the stability of the edited desk. As another example, a structure of an edited desk, such as the area of the ground that contacts the edited desk, or the number of spots where the edited desk and the ground contact, may be used as a criterion for determining the stability of the edited desk.

According to another embodiment, the device 100 may provide a recommendation list of compatible constituent articles, based on the prices of the compatible constituent articles. For example, when the conditions of constituent articles other than the price are the same, the device 100 may provide, as a recommendation list, constituent articles of which prices are less than or equal to a predetermined reference. As another example, the device 100 may include, in the recommendation list, constituent articles of which prices are less than or equal to a predetermined reference or constituent articles of which prices are equal to or greater than a predetermined reference, based on a user input.

According to another embodiment, the device 100 may provide a recommendation list of compatible constituent articles, based on the sizes of the compatible constituent articles. For example, when the target article is a desk and a constituent article included therein is a drawer attached to the desk, the device 100 may include, in a recommendation list, only drawers of which sizes are compatible with the size of the drawer of the desk which is the target article.

According to another embodiment, the device 100 may provide a recommendation list of compatible constituent articles, based on a connection relationship between the target article and each constituent article included in the target article. For example, the device 100 may include only constituent articles connectable to the chair, which is the target article, in a recommendation list. Constituent articles unable to be connected with the target article may be excluded from the recommendation list. For example, when the target article is a chair to which only wooden legs are connectable, only wooden leg types may be included in the recommendation list of constituent articles.

According to another embodiment, the device 100 may provide an image representing an operation of a constituent article included in the target article according to the function of the target article.

For example, the device 100 may provide an image representing an opening or closing operation of the drawer of a desk, which is a target article. As another example, the device 100 may provide an image representing a tilting operation of the back of a chair, which is a target article.

According to an embodiment, the device 100 may edit the shape of the target article, based on a user input via the GUI. For example, the device 100 may replace a constituent article included in the target article, based on a user input. As another example, the device 100 may change the color of the target article.

A detailed editing method will be described later with reference to FIGS. 7-17B.

In operation S240, the device 100 may generate the 3D printing information. According to an embodiment, the device 100 may edit the shape of the target article, based on a user input via the GUI provided in operation S230, and may generate printing information used to 3D print the edited target article.

According to an embodiment, the device 100 may generate printing information used to 3D print the edited target article. A 3D printer connected to the device 100 may 3D print the edited target article by using the printing information acquired by the device 100. The device 100 may generate printing information that is necessary for performing 3D printing on the edited target article. The device 100 may transmit the generated printing information to the 3D printer.

According to an embodiment, the device 100 may generate manual information representing a method of assembling the edited target article. For example, the device 100 may provide the manual information in the form of at least one of a text and an animation.

FIG. 3 illustrates an example in which the device 100 according to some embodiments acquires an image.

According to an embodiment, the device 100 may acquire a basic image, based on a touch input made on a screen of the device 100. For example, when a user makes a sketch on a screen on which a touch input is possible, the device 100 may determine an image drawn via a received touch input as the basic image. As another example, the device 100 may determine an image acquired via a sketch input as the basic image. A sketch input according to an embodiment may denote an input obtained by a user making a sketch via a touch on a screen where a touch input is possible. A sketch input according to another embodiment may denote an input obtained by the device 100 recognizing a sketching operation of a user.

The basic image may be a two-dimensional (2D) image or a 3D image. For example, the device 100 may recognize a sketch input of the user as a 3D image and acquire the 3D image as the basic image.

According to another embodiment, the device 100 may acquire the basic image via photography.

For example, when a specific area within a captured image is selected by the user, the selected image area may be determined as the basic image.

As another example, when the same object is photographed at different angles several times, a plurality of 3D images may be acquired from the photographed object and may be determined as the basic image.

When the same object is photographed at different angles several times, the device 100 may provide a description of photographing directions. For example, the device 100 may provide a description that guides photography in 6 directions or a description that proposes panoramic photography.

According to another embodiment, the device 100 may determine a captured image as the basic image. For example, the device 100 may determine an image obtained by photographing a furniture image found from the Internet, as the basic image. As another example, the device 100 may determine a furniture image, which is a part of a captured image, as the basic image.

According to another embodiment, the device 100 may determine an image downloaded from the Internet, as the basic image. For example, the device 100 may download an image via a search from the Internet and may use the downloaded image as the basic image.

According to another embodiment, the device 100 may edit the basic image. For example, the basic image may be edited according to a user input such as addition or deletion of a dot, a line, or a side, a change in the color of the basic image, or a change in the thickness of a line. According to an embodiment, the device 100 may provide an edition tool for editing an image.

FIG. 4 illustrates an example in which the device 100 according to some embodiments acquires an image from a server.

According to an embodiment, the device 100 may acquire an image from the server. For example, the device 100 may provide images found using a keyword input by a user. One of the found and provided images may be determined as a basic image. A keyword according to an embodiment may be received according to categories. For example, a keyword input to a second search box may be limited to a subordinate word of a keyword that is input to a first search window. As another example, a keyword “desk” may be input to a first search box 410, a keyword “H-type desk”, which is a type of desk, may be input to a second search box 420, and a keyword “hardwood desk”, which is a type of H-type desk, may be input to a third search box 430. In this case, the device 100 may provide a result of a search for hardwood desks from among H-type desks. For example, the device 100 may acquire, from the server, frequently-searched images from among images of hardwood desks included in an H-type desk, and display the frequently-searched images on the screen of the device 100.

According to an embodiment, the device 100 may acquire and display at least one image of a target article corresponding to an input keyword.

According to an embodiment, a candidate image of the target article may denote at least one image determined according to a user input. For example, the candidate image of the target article may include an image that is similar to the basic image by a predetermined reference or greater from among images stored in the device 100. As another example, the candidate image of the target article may include a predetermined number of images from among images that satisfy conditions of keywords input by the device 100.

According to an embodiment, the device 100 may determine one of the displayed candidate images of the target article as an image of the target article that is to be edited, based on a user selection. The device 100 may provide a tool capable of editing the image of the target article determined based on the user selection, and a detailed editing method will be described later with reference to FIGS. 7-17B.

The number of input keywords may be previously determined. For example, the device 100 may receive a keyword and provide a result associated with the received keyword, or receive a plurality of keywords and provide a result associated with the received keywords.

The categories of input keywords may be previously determined. For example, when a keyword regarding furniture is input, the input keyword may include at least one of a furniture name, a furniture type, a furniture material, and a thickness of a plywood that forms the furniture.

According to an embodiment, the device 100 may search for and acquire an image of a target article that satisfies the input keyword. The device 100 may acquire, from the server, information about the target article that satisfies the input keyword.

According to another embodiment, the device 100 may search for and acquire an image of a target article by using both a keyword and a voice. For example, the device 100 may recognize a voice of a user via a user input, and display a search result that satisfies a condition corresponding to the recognized voice of the user. The search result may include candidate images of the target article.

According to another embodiment, the device 100 may search for not only the target article but also the constituent articles included in the target article. For example, when the target article is a chair, the device 100 may search for a sitting mat that is not included in the constituent articles of the chair.

FIG. 5 is a flowchart of an example in which the device 100 according to some embodiments determines a target article.

In operation S510, the device 100 may acquire a basic image. Since operation S510 corresponds to the above-described operation S210, a detailed description thereof will be omitted herein.

In operation S520, the device 100 may acquire image parts by splitting the basic image acquired in operation S510. Image parts according to an embodiment may mean a plurality of image parts into which the basic image is split.

When the device 100 acquires the image parts by splitting the basic image, a predetermined criterion may be used. A criterion used to acquire the image parts may be previously determined according to the types of article included in the basic image. For example, when an article included in the basic image is recognized as a chair, the chair may be previously determined to be split into a chair back part, a seat part, and a leg part. As another example, when the article included in the basic image is a bed, the device 100 may acquire, as the image parts, a mattress part and the other part into which a bed image is split. As another example, the device 100 may acquire image parts for each of constituent articles into which each article is splittable.

In operation S530, the device 100 may determine a target article from an article list by using at least one of the basic image acquired in operation S510 and the image parts acquired in operation S520.

For example, a chair back image from among a plurality of displayed chair back images may be selected according to a selection input of a user.

The controller 2330 may provide the recommendation list according to a predetermined criterion. For example, the controller 2330 may provide the recommendation list of compatible constituent articles, based on stability of the target article edited by the constituent articles included in the recommendation list. The target article edited by the constituent articles included in the recommendation list may mean a target article that has been edited to include one of the constituent articles included in the recommendation list as a component of the target article.

Stability of an article according to an embodiment may mean a value representing a degree to which the shape or location of the article is maintained without being deformed when an external force is applied to the article.

When a constituent article included in the recommendation list is used as a constituent article of the target article, stability of the target article may be maintained to a predetermined reference or greater. For example when the controller 2330 provides a recommendation list for wooden legs which are a constituent article of an office chair, which is a target article, the controller 2330 may include only wooden legs of which stability is equal to or greater than a predetermined reference when being used in the office chair, which is the target article, in the recommendation list. Stability of the office chair edited by wooden legs included in the recommendation list may be maintained to a predetermined reference or greater. The office chair edited by the wooden legs, which are a constituent article included in the recommendation list, may mean an office chair including the wooden legs, which are a constituent article included in the recommendation list, as the constituent article. Stability of an edited target article according to an embodiment may be determined based on at least one of a location of the center of gravity of the target article edited by a constituent article included in a recommendation list and an internal structure of the target article. For example, a height of the center of gravity of a desk edited by a chair back included in a recommendation list may serve as a criterion for determining the stability of the edited desk. As another example, a structure of an edited desk, such as the area of the ground that contacts the edited desk, or the number of spots where the edited desk and the ground contact, may be used as a criterion for determining the stability of the edited desk.

According to another embodiment, the controller 2330 may provide a recommendation list of compatible constituent articles, based on the prices of the compatible constituent articles. For example, when the conditions of constituent articles other than the price are the same, the controller 2330 may provide, as a recommendation list, constituent articles of which prices are less than or equal to a predetermined reference. As another example, the controller 2330 may include, in the recommendation list, constituent articles of which prices are less than or equal to a predetermined reference or constituent articles of which prices are equal to or greater than a predetermined reference, based on a user input.

According to another embodiment, the controller 2330 may provide a recommendation list of compatible constituent articles, based on the sizes of the compatible constituent articles. For example, when the target article is a desk and a constituent article included therein is a drawer attached to the desk, the controller 2330 may include, in a recommendation list, only drawers of which sizes are compatible with the size of the drawer of the desk which is the target article.

According to another embodiment, the controller 2330 may provide a recommendation list of compatible constituent articles, based on a connection relationship between the target article and each constituent article included in the target article. For example, the controller 2330 may include only constituent articles connectable to the chair, which is the target article, in a recommendation list. Constituent articles unable to be connected with the target article may be excluded from the recommendation list. For example, when the target article is a chair to which only wooden legs are connectable, only wooden leg types may be included in the recommendation list of constituent articles.

According to another embodiment, the controller 2330 may provide an image representing an operation of a constituent article included in the target article according to the function of the target article.

For example, the controller 2330 may provide an image representing an opening or closing operation of the drawer of a desk, which is a target article. As another example, the controller 2330 may provide an image representing a tilting operation of the drawer of the chair, which is the target article.

According to an embodiment, the controller 2330 may edit the shape of the target article, based on a user input via the GUI. For example, the controller 2330 may replace a constituent article included in the target article, based on a user input. As another example, the controller 2330 may change the color of the target article.

A detailed editing method has been described above with reference to FIGS. 7-17B.
